A Study on the Friction Compensation in CNC Servomechanisms by Fuzzy Logic Control

퍼지논리 제어에 의한 CNC 서보기구의 마찰보정에 관한 연구

This paper introduces a friction compensation fuzzy logic controller, which utilizes a rule-based approach. The paper explains the algorithm of the proposed controller and compares it with a conventional PID controller in simulations and experiments. For the experiments, the two control algorithms were implemented on a 3-axis milling machine in contour milling. These simulation and experimental analyses show that the proposed fuzzy logic controller has superior performance over conventional PID controllers In terms of part contour accuracy.
